People have been banned for clearing their logs, so it seems Nintendo also checks for "continuity"
i.e. if some logs your Switch sent before go missing, it means you did something questionable to get rid of those logs.
So IMO, just having a NAND backup is not enough.
It'd also be safest if you NEVER go online from when the NAND backup was made, until the point it is restored.

So as for your question, maybe you can use ChoiDuJour with your biskeys to create a clean SYSTEM partition, and along with an empty USER partition, to create a "clean" NAND. It's not necessarily a "safe" NAND though.

But if your logs were cleared and you then did a factory restore would that still trigger anything on Nintendo’s part as your “new” console would be accepted as not having any logs yet?

I just want to help my friend get their clean nand backup for eventual emunand or error avoidance. So I’m not saying it’s something they’ll go online with straight away but something cleaner than what they already have.

There is no real way to get a clean nand again, not even a restore. My best guess is to clear the logs with dreport (The SDCardfiles should do fine) and boot Hekake and clear. Then factory reset your switch and format your SDCard. Oh and never boot Horizon while you doing the Hekake parts, but instead boot Recovery Mode (it's power + Vol - without a jig!), and from there do th factory reset. Then you can boot your Switch normally because in theory it should look like you had a problem with your Switch and manage to get it to work by doing a factory reset.
